1. 在pom.xml
中加入Swagger2的依赖
<!--加入Swagger2的依赖--> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>2.2.2</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>2.2.2</version> </dependency>
2. 在Application.java
同级创建Swagger2的配置类Swagger2
import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import springfox.documentation.builders.ApiInfoBuilder; import springfox.documentation.builders.PathSelectors; import springfox.documentation.builders.RequestHandlerSelectors; import springfox.documentation.service.ApiInfo; import springfox.documentation.spi.DocumentationType; import springfox.documentation.spring.web.plugins.Docket; import springfox.documentation.swagger2.annotations.EnableSwagger2; @Configuration //让Spring来加载该类配置 @EnableSwagger2 //启用Swagger2 public class Swagger2 { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo())//用来创建该Api的基本信息(这些基本信息会展现在文档页面中) .select() //用来控制哪些接口暴露给Swagger来展现, //本例采用指定扫描的包路径来定义,Swagger会扫描该包下所有Controller定义的API,并产生文档内容 //(除了被@ApiIgnore指定的请求) .apis(RequestHandlerSelectors.basePackage("com.example.demo1.web")) .paths(PathSelectors.any()) .build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("Spring Boot中使用Swagger2构建RESTful APIs") .description("更多Spring Boot相关文章请关注:https://www.cnblogs.com/yangjiming/category/1240129.html") .termsOfServiceUrl("http://www.cnblogs.com/yangjiming/") .contact("Mr.yang") .version("1.0") .build(); } }
3. 在代码中添加文档内容,通过@ApiOperation注解来给API增加说明、通过@ApiImplicitParams、@ApiImplicitParam注解来给参数增加说明。
import com.example.demo1.domain.User; import io.swagger.annotations.ApiImplicitParam; import io.swagger.annotations.ApiImplicitParams; import io.swagger.annotations.ApiOperation; import org.springframework.web.bind.annotation.*; import java.util.*; @RestController @RequestMapping(value="/users") // 通过这里配置使下面的映射都在/users下 public class UserController { static Map<Long, User> users = Collections.synchronizedMap(new HashMap<Long, User>()); @ApiOperation(value="获取用户列表", notes="") @RequestMapping(value={""}, method=RequestMethod.GET) public List<User> getUserList() { List<User> r = new ArrayList<User>(users.values()); return r; } @ApiOperation(value="创建用户", notes="根据User对象创建用户") @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User") @RequestMapping(value="", method=RequestMethod.POST) public String postUser(@RequestBody User user) { users.put(user.getId(), user); return "success"; } @ApiOperation(value="获取用户详细信息", notes="根据url的id来获取用户详细信息") @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long", paramType="path") @RequestMapping(value="/{id}", method=RequestMethod.GET) public User getUser(@PathVariable Long id) { return users.get(id); } @ApiOperation(value="更新用户详细信息", notes="根据url的id来指定更新对象,并根据传过来的user信息来更新用户详细信息") @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long", paramType="path"), @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User") }) @RequestMapping(value="/{id}", method=RequestMethod.PUT) public String putUser(@PathVariable Long id, @RequestBody User user) { User u = users.get(id); u.setName(user.getName()); u.setAge(user.getAge()); users.put(id, u); return "success"; } @ApiOperation(value="删除用户", notes="根据url的id来指定删除对象") @ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long" , paramType="path") @RequestMapping(value="/{id}", method=RequestMethod.DELETE) public String deleteUser(@PathVariable Long id) { users.remove(id); return "success"; } }
1 public class User { 2 3 private Long id; 4 private String name; 5 private Integer age; 6 7 8 public Long getId() { 9 return id; 10 } 11 12 public String getName() { 13 return name; 14 } 15 16 public Integer getAge() { 17 return age; 18 } 19 20 public void setId(Long id) { 21 this.id = id; 22 } 23 24 public void setName(String name) { 25 this.name = name; 26 } 27 28 public void setAge(Integer age) { 29 this.age = age; 30 } 31 }
4. 完成上述代码添加上,启动Spring Boot程序,访问:http://localhost:8080/swagger-ui.html
